In the latest chapter of the ongoing legal saga between Oracle and Google, Oracle claims it should be awarded $2.6 billion for Google's alleged infringement of its intellectual property with regard to the Android mobile operating system.

An expert hired by Oracle, Boston University finance professor Iain Cockburn, calculated the figure as part of a court filing on Tuesday, Marketwatch reports. Previous filings did not indicate just how many "billions" of dollars Oracle sought in damages.

The filing was about as he-said, she-said as it gets:

Google falsely claims that Prof. Cockburn concludes that Oracle is owed anywhere from $1.4 to $6.1 billion in damages. He does not. His opinion is that the total damages that should be awarded to Oracle is $2.6 billion.

Google, of course, rejects Cockburn's estimate as "inappropriate," calling into question the methodology for calculating the figure and calling the figure inflated.

It's the latest round in a long legal battle in which Oracle says Google is infringing on the patents and copyrights within its Sun portfolio, which it acquired last year. The Android ecosystem has been under fire from several companies, including Apple, who attest that both software and hardware too easily mimic patents held by rival tech companies.
